YA + murder mystery = fast-paced plots without a bunch of existential fluff. We bit off our fingernails reading these books & series, even if they don't ACTUALLY start with a body.
I realize I am probably the only person in the whole world who didn't love this book. But since I am the only one, that means YOU WILL!
I love this series (three in a proper trilogy, then two more standalones) for the level of detail and some great red herrings for each new body.
Cadence is one of the cousins in a perfect, wealthy family who is clearly hiding something weird this summer on their annual trip. Check out the equally good but very different prequel, Family of Liars, too.
